Now I understand. Unfortunately the grid layout does not support this. You have 
to manually resort the widgets to be able to add another widget "in between".

Maybe you create a custom widget for this. A composite container with VBox 
layout and some additional service methods to be able to add the widgets. The 
functionality you want to use is not available out-of-the-box in qooxdoo.
